The Center for Land Use Interpretation in Los Angeles examines what they term “perpetual architecture” — several dozen cell structures scattered across the desert of the U.S. southwest holding radioactive hazards. These edifices are designed to exist forever — thousands of years from now, in a vastly different world, these may be the only remnant of our civilization. Below is the Green River Disposal Cell in Utah:
More than 30 of these disposal cells have been constructed over the last 25 years, primarily to contain radioactive contamination from decommissioned uranium mills and processing sites. They are time capsules, of sorts, designed to take their toxic contents, undisturbed, as far into the future as possible.
